Devialet Dione, an intensely immersive, all-in-one sound bar that’s equally advanced and intuitive. Seventeen autonomous high-end drivers deliver deep infrabass and crystal-clear treble, while eight built-in SAM®-powered subwoofers remove any need for additional equipment.

Devialet Dione is powered by a suite of patented Devialet technologies: SPACE provides a distinctly enveloping specialization effect, while AVL equalizes sound levels in real time.

On the aesthetic front, Devialet Dione boasts an incomparable thinness-to-performance ratio and an iconic central ORB that adapts to whatever in-home placement you choose. A plug-and-play way to enjoy a vivid, cinematic viewing experience in a 3D, 5.1.2 configuration. See the sound.

Dione runs on the DOS2 software ecosystem, meaning set-up and customization are seamless in the Devialet App. Dione also integrates into a Phantom multi-room configuration through Airplay 2. This set-up is also possible for any Airplay 2 enabled speaker if you use iOS.

Devialet was born in 2007 as a response to the paradox that whilst music has never been so accessible in terms of volume, the quality of the sound itself, and the way technologies manage to restitute it, remains questionable. The purity and detail that make music what it is, continues to elude us.

The company name is a reference to engineer Guillaume Vialet, a companion of Diderot and contributor to the French Encyclopedia. Vialet is widely known as one the intellectuals who, through their intellectual, cultural and scientific commitment, contributed to the betterment of the world.
